Consider the following .
The tableau corresponds with a step of the SIMPLEX
method applied to the previous problem.
Company is planning to replace its current electrical infrastructure with a new
special system. Since the new system has more capacity it is not necessary to
maintain all the current connections. The manager wishes to decide which pairs
of offices should be directly connected in order to ensure that every office is
connected (directly or indirectly) in the new system. The figure shows the
current infrastructure: the letters represent the offices and the arcs, the
connections. The numbers represent the distances between the corresponding
In order to minimize the cost: What are the
offices that must be directly connected? Assuming that for the new system is
required 3 units of cable for each unit of distance, how many units of cable
should be purchased by the company? Justify with the calculations performed.
The town hall of a city wants to open some
recreational centers. It has been analyzed 3 options. The opening cost and the
capacity of each center are listed below.
selected recreational centers must be hosting the students from 5 schools. In
the table below is summarized the number of students at each school.
school must be assigned to only one recreational center. And the capacity of
each center must be respected. What are the recreational centers that must be
open in order to minimize the opening cost?
